Three problems related to speed control cable have been reported for the 1997 Ford F-150. The most recently reported issues are listed below.
I started to pass a pickup in front of me. As I got along side I noticed I was already up to 70 mph. I stepped on the brake and pushed the coast and off buttons for the cruise. I let off the brake slightly and was now up to 90 mph. I pushed the brakes hard and turned the key off, coasting to the shoulder. When I turned it back on it went to full throttle instantly. I disconnected the cable for the cruise and turned it on. The engine idled and the cruise cable pulled all the way in. The next day I checked the cruise cable and it was not pulled in with the engine running. I was lucky there were no cars on the highway in front of me when it happened. In the last week the Ford dealer has done nothing.
Throttle cable sticks in wide open positon, causing a loss of throttle control. Driver able to use brakes to stop vehicle and shut off engine. Dealer not contacted yet.
Throttle stuck and vehicle accelerated forward. Driver could not make the vehicle slow down by applying the brakes. Driver had to downshift gears in order to stop vehicle. Dealer could find the cause.
